cl i (011160-132) This invention relates toawningsespecially I designed for use over windows, doors, and tranm fl n s ofasim anna e- One object is to provide an awning that may be made of rigid material such as metal, plastics or other similar material in contrast to nonrigid material as commonly used such .as canvas and various kinds of fabrics.

Another object of my invention is to provide an awning of the nature indicated that includes a shading-housing for certain shading extensible parts to be fixedly mounted in position over the opening to be shaded.-

A further object of my invention is to provide an awning of the nature indicated that may be extended or retracted without the use of complicated mechanism heretofore used such as ropes, pulleys, gears and shafts, chains and sprockets with their mountings, requiring considerable effort and time to manipulate, and requiring some expense to keep in working order.

A still further object of my invention is to provide spring tension means for holding the awning in extended or open position, and also so arranged as to hold the awning in closed position, and to carry a portion of the weight of the shading members so that the said members may be opened or closed with but little eiiort.

Finally, it is the object of my invention to provide an awning of the character indicated that will be simple in form and construction, that consists of few parts, that is strong and durable, and highly efiicient in its practical application.

In the drawing:

Figure 1 is an end elevation of the awning in an operative position.

Figure 2 is a front elevation of one end portion of the awning shown in Figure 1.

Figure 3 is view on line 3-3 of Figure 1.

Figure 4 is a sectional view on line 4-4 of Figure 2.

Figure 5 is a sectional view on line 5-5 of Figure 1.

Figure 6 is a sectional view on line 6-6 of Figure 3.

Figure 7 is a sectional view on line 1-! of Figure 2.

Referring now more particularly to the drawing, I show at l the housing or hood portion made in the form of an inverted U havin its rear edge welded to a flange 2 which encompasses-the opening in the building upon which it is to be mounted. The top portion of member I is positioned at an angle to flange 2 and slopes downwardly therefrom with a downwardly extending lip or flange at 3 extending along this bottom edge as shown. At 4 is shown the intermediate member having an upwardly turned flange formed on its top and inner edge to en age the inner surface of flange 3 as 5, and a downwardly turned flange or lip on it lower forward edge as 6. The member 4 is also in the form of an inverted U and the lower ends of its side portions are pivotally connected to the lower side portions of portion I by means of a pivot I.

A third or bottom member 8 is also made in the form of an inverted U and to fit within the member 4 with the lower end of its side portions pivoted on the pivot i. It has a flange 8a extending upwardly from its rear edge to seat against the rear surface of flange E and a bottom or front flange turned inwardly a at 9 to form a finishing edge.

Mounted upon the lower end of the side portion of member 8 as an integral part thereof is an angularly directed lever I ll.

The side portions of the U shaped members have outwardly directed flanged on their forward edges as at H, and these flanges engage during the operation of raising the said members.

At [2 is shown a tension spring connected at one end to a point on the lever H], as It, spaced from the pivot I about which it turns. The other end of the spring is attached to a strip M which is hooked over the top flange of member 1.

The two ends of the device are identical in form and arrangement except that the lever is provided at one end only and this lever provides a handle as shown.

In a normal retracted position the parts are in the position shown in Figure 4, the part I functioning as a housing into which the parts 4 and 8 are turned when not in use. The several parts are held in this postion by the spring I 2 exerting an upward pull on lever Iii.

When it is desired to extend the parts: 4 and 8 a downward pull is applied to lever It, and being a part of member 8 the said member is swung about pivot 7 until flange 8a engages flange 6 and carries member 4 forwardly. This movement continues until the point I3 passes the dead center l 4 when the sprin pulls the lever in upwardly and holds the members 4 and 8 in their extended position. When the lever to is moved in the opposite direction and member 8 is swung back toward the housing the flanges El engage and the two members A and 8 are carried back into the housing as a unit.

While the part I functions as a housing for the members 4 and 8 it also acts as a shade mem-v her and is operative as such at all times. This housing membe I provides a support for all of the rest of the awning and constitutes substantially one-third of the shading elements thereby making the device extremely simple in construction. The construction as disclosed consists of only four parts, the hood member, the intermediate shading member, the outer shading member with the lever, and the spring member.

The device is exceedingly easy to operate owing to the tension spring. When the lever 10 is operated to extend members 4 and B or to return them into the housing I, the spring It! supports a major portion of their Weight so that they are floated from one position to the other Without material effort on the part of the operator, and owing to the position of the spring attachment to the lever they are securely held in the open or closed position as desired.

Havin thus described my invention, what I claim as new and desire to protect by Letters Patent; is: I

In an awning of the type disclosed, a U shaped supporting and shading member, a, plurality of U shaped shading members pivotally associated therewith at the lower ends of their side portions, a lever attached to the lower portion of the side of the outermost shading member, and a tension spring operatively inserted between said lever at a point adjacent to its attachment to the shading member and the top portion of the supporting member.
